Therefore, armed with that knowledge, you should work your ass off to make sure that you don't fall into that category so that you can benefit most.
Many pro artists (such as Dave Rapoza) were self-taught or had shitty art school experiences and had to motivate themselves. If you are choosing not to go there because the teachers won't hold your hand if you're struggling and you don't want to work harder and work on your own learning to get out of that kind of treatment, then to be perfectly honest, that's your problem, not the school's.
Use it as a motivator. It's a competitive industry. You might feel bad because your classmates are getting harsh treatments for falling behind but honestly, you're all fighting for the same jobs. AND, from the sounds of it, it doesn't sound like you have enough time for a social life, so how other people are faring if they're worse off than you should be really inconsequential.
If it were to happen to me, I'd take it not as a blow to my ego but a kick in the pants for me to work harder. Therefore, I am not worried.
